FirstName什么意思

The XML document is shredded,and each bound-out column (title,publisher,firstname,lastname) is converted to the database code page.
XML 文档被分解,每个绑定列（题目、出版社、名、姓）被转换为数据库代码页.
This will be,technically speaking,a second key and we can make ID the primary key of the DIRECTORS table while asking the DBMS to ensure that firstname and surname remain unique across the table.
ID也是表的键,我们可以把它设为DIRECTORS表的主键同时可以利用数据库管理系统确保表中的名字和姓氏是唯一存在的.
As a result,the directory catalog is very small in size,but can only be sorted by firstname or lastname,which must be designated when creating the directory catalog.
因此该目录编目非常小,只能按姓或名排序,在创建目录编目时必须指定排序方法.
